Trimestria

The Trimestria extension files with the Agencia Tributaria the return you prepared and confirmed in Trimestria, from your own browser and with your own certificate. No apoderamiento is needed: you file yourself, as the holder, just as at the sede. How it works - On the return's page you press "File from my browser". - A tab of the Agencia Tributaria opens and the browser asks you to choose your certificate. - The extension sends the return you confirmed from that tab, closes the tab and hands the Agencia's answer back to Trimestria. Your certificate stays with you The certificate, its key and its password never leave your device: the browser uses them and the extension never sees them. What it does not do - It keeps, logs and sells no data: it only carries to the Agencia Tributaria, when you ask, the return you confirmed, with your NIF, name and figures, and hands the Agencia's answer back to Trimestria. - It answers only the Trimestria page and talks only to the Agencia Tributaria. - It decides nothing: it sends what you confirmed, as it is. Works in desktop Chrome and Edge. Help: support@trimestria.es
